The Vantrue N4S is a three-channel dash cam: one unit records the road ahead and the inside of the car, and a separate camera records behind. It uses three STARVIS 2 sensors, has four parking modes, and offers 5GHz Wi-Fi and GPS logging. Here is what its specifications mean for everyday driving, rideshare work and parking.
Three cameras, three views
The N4S records in 2.7K at the front and 1440p in the cabin and at the rear. 1440p is 2560 x 1440 pixels, and 2.7K is a step above that in width, so the front camera, which matters most for the road ahead, gets the most detail.
The lenses are wide: 158° at the front, 165° in the cabin and 160° at the rear. A wider angle covers more lanes, kerbs and the sides of the car, though objects at the edges of a very wide view look smaller and slightly curved.
Low light: STARVIS 2, HDR and PlatePix
All three cameras use STARVIS 2 image sensors, which are designed for sensitivity in low light. Triple HDR (high dynamic range) helps with harsh contrast, such as bright headlights against a dark road, by keeping detail in both the bright and the dark parts of the picture.
PlatePix is Vantrue's processing for licence plates, which it says sharpens them on dark streets, in tunnels and in garages. Plates are often the hardest detail for any dash cam to capture at night, and results still depend on distance, speed and lighting.
Parking modes
The N4S has four parking modes. Motion detection keeps 10 seconds of pre-event recording, so a clip shows what happened just before the camera was triggered. Collision detection automatically locks the footage after an impact so it isn't overwritten. Low-bitrate and low-frame-rate modes make files smaller to extend recording time.
Parking mode needs a hardwire kit, sold separately. A hardwire kit connects the camera to the car's fuse box so it has power while the engine is off. Many kits include a low-voltage cut-off to protect the car battery, so check the one you choose, and have it fitted professionally if you're not comfortable working with the fuse box.
Wi-Fi, GPS and memory cards
Over 5GHz Wi-Fi, clips download straight to your phone, so you don't need to remove the memory card to see or share them. Quad-mode GPS, including BeiDou positioning, logs speed, location and time alongside the footage. The camera also gets firmware updates over the air.
It takes microSD cards up to 1TB, sold separately. Dash cams record in a continuous loop, writing over the oldest files, which is hard on memory cards. High-endurance cards, designed for continuous recording, generally cope better.
Installation and the rotating rear camera
A magnetic mount, static cling film and cable clips make installation tool-free, with the wires tucked out of sight. The rear camera rotates 360°, so it can face the traffic behind or turn inward to keep an eye on cargo, luggage or pets. Vantrue advises following the manual when connecting the rear camera's wiring, since a loose connection can cause faults.
The N4S uses a supercapacitor rather than a battery and is listed for -4°F to 140°F (about -20°C to 60°C). Supercapacitors generally cope better with the heat inside a parked car than small lithium batteries. Vantrue lists an 18-month warranty.
Who it suits
It suits rideshare drivers who want a record of the cabin as well as the road, daily commuters, and anyone who wants front, interior and rear coverage from one system, including while parked.
What to check before you buy
- Parking mode: allow for a hardwire kit and its installation if you want recording while parked.
- Memory card: choose a microSD card made for continuous recording; one isn't included.
- Local rules: check rules on windscreen mounting and on recording passengers, especially audio, where you drive.
- Rear camera: plan the cable route from the front unit to the rear of your vehicle.
- Phone: check that your phone can connect to the camera over 5GHz Wi-Fi for downloads.
